Login Licensing Support
Login based licensing requires an active internet connection.
In Houdini 18.5 and later, Houdini has the option to use login licensing. Login licensing requires the user to be constantly logged in with their sidefx account otherwise it works similar to traditional licensing setups.
The recommended users for login licensing are indie and education users. In a studio setup the requirement to be constantly logged in may pose as a challenge and a traditional license server does not have this requirement.
Follow these steps to start using login licensing:
Login to your sidefx account File menu ▸ Login….
Change the license server to https://www.sidefx.com/license/sesinetd File ▸ Change License Server….
All uninstalled entitlements act as login licenses. This gives you freedom to customize your configuration to use all licenses in the cloud, on-site, or a mix using server chaining.
Browser based Houdini License Administrator
In addition to login licenses, you can view your licenses through the browser and control your license setup.
If you go to https://www.sidefx.com/services/sesinetd, this page uses your currently logged in profile as the login licensing profile. This webpage will also display all of your licenses both from your server list prior to visiting sidefx.com and all of your unredeemed entitlements.
Browser based Houdini License Administrator requires an active internet connection and a running hserver.
API Key licensing
API key licensing gives you the freedom of login licensing without the need login through hkey. This is a great option for render farms or other setups that do not have an artist sitting at the machine that can keep logging in when required. To generate api keys either open hkey to Help ▸ View Api Keys Online or go to https://www.sidefx.com/oauth2/applications/ and select
Register a new application.
These keys will get refreshed when needed as long as the credentials are valid.
To enable api key support for hkey and sesictrl add
HOUDINI_API_KEY_FILE="<file location>" to the houdini.env file. The format of the file is
www.sidefx.com <client id> <client secret>.
To use API keys with hserver place the api key in the options file. See hserver for further details on how to setup API keys for hserver.
